Out-of-bounds Read vulnerability in Apache Fory C++ deserialization. (CVE-2026-71560)
An out-of-bounds read vulnerability exists in Apache Fory C++ deserialization affecting versions from 0.14.0 up to but not including 1.5.0. The flaw occurs when deserializing structs containing tagged integer fields, potentially leading to information disclosure or denial of service. The issue is fixed in Apache Fory version 1.5.0. Applications not using Apache Fory C++ or not using tagged integer fields are not affected.
AI Analysis
Technical Summary
CVE-2026-71560 is an out-of-bounds read vulnerability in the Apache Fory C++ library during deserialization of structs with tagged integer fields. Versions from 0.14.0 before 1.5.0 are affected. A crafted input payload can trigger an out-of-bounds heap read in the tagged integer fast-path deserializer, which may cause information disclosure or denial of service. The vulnerability is addressed by upgrading to Apache Fory 1.5.0.
Potential Impact
Exploitation of this vulnerability can lead to information disclosure or denial of service due to out-of-bounds heap reads during deserialization. This impacts applications using vulnerable versions of Apache Fory C++ that deserialize tagged integer fields. Systems not using tagged integer fields or not using Apache Fory C++ are not impacted.
Mitigation Recommendations
Users should upgrade to Apache Fory version 1.5.0 or later, where this vulnerability is fixed. Applications that do not use Apache Fory C++ or do not deserialize tagged integer fields are not affected and require no action.
